To all fio/low may concern:

Be it known that l, ,lossen S. BARTLEY, a Citi en ot the United States of America, res-ding at Denver, in the county ot leuver and tste of Colorado, have invented certain new and useful luiproveineiits in Crushing;- Mills, of which the following is a, specification. i

My inventiony relates to crushinganills of the class employed to coinminute ore, rock, cement and other similar substances and its 'tival ohjeet resides in the provision io.- uil. 'eh one or more niullers are ported in oiroular inortars which l L. tod to rotate shout a horizontal axis. ther iunior objects ot thel intention will 4 the following description, reference being; had to the accompanying; drawings in the Various views ot' uf'hieh like parts are similarly kdesignated and in r/hioh-m Figure l, ep 1eents a longitudinal vertiully appear in simplest torni, i nal section of the revolving element comprised in the invention, in which two mor` )port of duplex mailers. l? a section similar showing the-method of asseinlling a larger number ot' inullers in one mill, Fig. l, a similar section ot" the refolifing element oil a mill are spherieal, Fig. 5, a iuginentary sectional view oi' a mortar and the therein supportedmullet, the oontaeting circular surfaces of which are flat, Fig. t5, a longitudinal section of the revolving; element ot the niill shown in l? l, provided with ineaus i'or returning a portion oi' the material distharged troni the mortar. iV to the saine for further treatment, Fig: 7, an end View ot the iuill and Fig. 8. a trans Yerseseeiioii taken along the line 8F38 Fig'. l.

tires have at their outer edges, eircuuiferential flanges T to which the heads 8 and 9 ends of the shell :2, are fastened hyineans of bolts 10. rlhe head 8 at the feed end ot the shell has a central inletopeninpj formed by an outwardly projecting necky l). which, in practice, coniniunioates With a chute or other appliance through which the material to he erusheth'is conducted to the inill, and the opposite head 9 at the discharge end of the inill, has a central, outwardly projecting nozzle 13 Which-normally is closed by means of a cap 14. The head Q'is furthermore proifidecl with a 'plurality of aperti'ires i5 which, if so desired inay he Closed by means of plugsl, and the nozzle. lil as 'Well as the cap 1.4, are likewise formed 'with perforations through Whih the material discharged from the mortar may pass into a conical receiver 17 which is tasteneol at its edge around a circular flange 18 'which projects co-neentiieally outwardly :from the head Q. The receiver 1T preteen ably osunposed of Wire screen or other foraininetr suhstai'ioe, for the purpose oil disoliarg'inpj the eoniu'xinuted matter, While the ini-ll is in operation.

The central openings ot the two heads S and 9 conununieate respectively with the interiors of inwardly projectii'ig hollou7 bosses i9 and 20 formed integral with thesaid extreme ends, guiding;l surfaces lll and Q03 which iu the operation. serre to maintain the nulller supported in the mortar` against lateral displacement, as will hereinafter he described and the eircurnterential 'walls ot these bosses lll and 2() are formed with openings through which the material may pass into and out oli the shell.

he inner surface of the mortar 'l which occupies the recess torinedghy the expanded *portimi of the shell, is eonea've and its edges are either in f" .ment with or slightly helou' the interior surfaces of the end portions of the shell.

A mullet' Q'l whose oiivuiuterential surextend contiguous to the and Sa at the inner ends ot 19 en@ 2Q, fertile purpose of maintaining the militer against intensi displacement, Whifiotfne miii in operation,

The enti port-ions of the sieit i, at opposite sies of the mortel' i are provided. with 'a seiies of tinck-ts 2e .vynicii nrizxnged consecutively I the pertions, to coin-'ey the niotei'isi fed thereinto, .to peints sheil, Wtieie it. is disehoiged upon the exterioi surface vof en :annular piste 25 which is secneA eoneentiicaiiy .in spe-Ceci felation to the seid end portions by means of struts 26 and each of which has upon its outer suifaee a series of consecutively arranged, oblique riiies 2? which guide the material toward the discharge end of the mili.

The mstei'isi fed into the mill t-hrongia the sentirei neck l2 and. the eicuinfeientiai ports in the l), is thus conveye by ineens of the arjaeentsei'ies of buckets 2e to s pointebove 'the inniiei 91, and is thi'engii the instrumentality of the iiiies F27' on theeoiesponing snnnius .25, t'isebmged into the mortal' in front of the mailer, and the eoniniinuted mette? iischarge from the moi'tsr in the' sinne mennen conveyed toward the speitured head 9 thongh which it, passes into the receiver 1T The shell 2 is supported to fevoive about e, hoiisontal exis coincident with its longitudinal axis, 'upon oileis 28 which engr-ige the circumferential surfaces of the tires 8, and are iotatsbiy supported in pairs, in bearing boxes 2f) upon a suitable oase 3G, and the seid movement is imported to theyshei by nieans of n pinion 3l which connects with a eonvenientljy ioeated motor and which meshes with an annule? gear-Wheel 32 coneent't'iooiiy secured upon the outer surface of the head et the feed-end of the sheii.

Instead of diiecting the oblique riies npon the onn'uiei piste Qt, towaid the dis charge end of the shell, they may be age-- ranged in the opposite cir-ection, as shown et 33 in Fig, G, for the pui'pose ot' i'e'suin ing` the larger constituents of the com minnted metter discharged from the mortar into the seme to be again subjected to the crushing action of the muiier 21.

i/Vhen the mili is coi'lstrueted with two inotars, es .is shown in Fig. 2, the resgieetive nniiei's ae connected to move in unison by means of a shaft. Se which, projecting beyond opposite sides thereof, carries et its extremities, the blocks 23 'which engage the guieting taces of the bosses 19 and 20 on the heads 8 and 9.

n the forni illustrated in Fig. 3, the shell carries fooi? consecutiveiy simnged monta-fs, sind the mailers supported therein we connected in peices in the manner shown in Fig. 2, the .outermost clocks 9S engagngthe guiding suzfaees of the respect-ive bosses 19 and 20 While those at the innerends of the the interior surfaces of,

In the forni shown in Figa e the Spherion?. rnuilers 35 engage each other and the guiding surfaces of the. bosses i9 'and 20cir'cnmferentrisiiy :ind 'thus obvia-te 'the use of 'the blocks Whiie. in'Fig. 5, the cic'umf surfaces of 'the mort-o1' 36 anti the ,millier 3, are Het instead of concave :and convex es site t'mse hereinbefore deseiibed.

` As the opera-tion of the mii has been ife- 'ei'ieci to :it intervals in the eoufse of the cieseription, it Wii oniy ice necessary to .ontiine it. briefiy at this point.. i

The material to be ciusieai is together with suitable quantity of Weten feet through the neck l2 into evoivng sneii 2 and. is by ineens of the buckets and the `i-iiies upon the corresponding ring 25, esiried nto'the mortar :it s point in iront of the millier which rotates by season of its Contact withv the mortal'. and which by its Weight .tas Weii 'as its otsry n1oveinent, crushes the material into minute pertieies which iow into the end portion of the siieli adjacent the aperture/:l hea, The ineness of the materiel to be discharged into the i'eceivel? is eteimined by'eiosing one or more of the outer seiies of openings in the heed 9 by ineens of the pings 16 for it Wiii be obseiveci, that, inasmuch es the shell is` continuously provided .with Water, the psitieles of' the coniminnte oie Wii 1oe. oies siied sceoifling' to their size moi weight, tile smziiier and iightei particles being heid in suspension neer the surface tile finiti contained in the siieli While the heavier metter sinks to the bottom tiiefeo. By ei'rzinging the fifties et the disci arge end of the sheii, in the manner shown in Fig. 6, these heavier particles are retained to the niort-si Whitey the lighter moitier, nesifei the exis off rota tion, is dischseged tin'ough the spent-unes in the piete 9 n the treatment of very herd substances, the numbers of lnuiei's may be increased to a. practically uniimited'extent, as shown in the fern' i'epiesented in. Figs1 2 and and the she-pe of the contacting suifeees of the mortels and the miniers, and the size of the istter may be varied to render the iniii snit-able foi` the treatment of inateiias of different characters.
